OSError: [Errno 99] error while attempting to bind on address ('::1', 17563, 0, 0): cannot assign requested address

I was trying to run the example WebSocket code and it crashes on this:

Exception in thread Thread-1:

The example I used can be found here

Can you give me the exact code you tried to run? Also could it be that there is still a process running that is blocking the port 17563?

[Arthurdw]

The code was an exact copy. (except that I replaced the client id and secrets with mine. No other proces was running on that port.

Hmm ok which OS are you using?

Distributor ID: Ubuntu
Description:    Ubuntu 19.10
Release:        19.10
Codename:       eoan

This seems to be related to some local service already using that port. Cant fix this.
